| 摘 要： | 从31种TCNQ离子自由基盐的粉末压片中,观察到Li-TCNQ、Mn(TCNQ)2·3H2O、Cu-TCNQ、Cu(TCNQ)2、Zn(TCNQ)2·xH2O和Ag-TCNQ有电开关效应.粉末压片的直径是5或8mm,厚度300-600μm,片的两面分别蒸镀Cu和Al电极.电压超过阈值5-8 V时,伏安特性出现突变,电阻值突然下降,从104-105Ω降至102-103Ω.高阻态(关态)与低阻态(开态)的电阻比值约几十到几千.

| Abstract: | Among 31 TONQ-ion-radical salts, electrical switching has been observed in powder compactions of Li-TONQ, Mn (TONQ) 2·3H2O, Cu-TCNQ, Cu (TCNQ) 2, Zn (TONQ) 2.xH2O and Ag-TONQ. These TONQ-ion-radical salt powder compactions were of 5 or 8mm diameter and approximately 300-600 μm in thickness with evaporated On and Al electrodes. The current-voltage characteristics revealed an abrupt decrease in resistance from 104-105 to 102-103 at a threshold voltage of 5-8 V. The ratio of Roff/Ron is tens to thousand times. |
